They also punish the bad guy. The difference with Taxi Driver is the one who is skilled in fighting is the girl and the guy is the one who direct. They are also a team of five not only two persons.

If there is a movie closer to The Man From Nowhere for its closeness then it would be The Suspect. Can't believe no one hasn't recommended it. Both movies are action packed. The main characters are equally skilled in combat and weapon. Both are facing tremendous amount of enemies to get back a person important to them. I rated both movies the same 10 when it's not easy for me to give 10 ratings. Just watch it and you'll know.

Both Action Comedy with male lead skilled in martial arts and fight against many then win, also both are very funny. The same level of quality.
